Yea 450's run cool to begin with. I think it loaded at ~50C on air. But now I have twice the amount of radiator heat dissipation with both push/pull HS Yates, and almost twice as better flow with the new pump. I decided not to put my chipset blocks, too much restriction. But I might mod the stock chipset heatsink and just put the VRM block on there, since I already have it.
It definitely is nice and cool
edit: also the gpu is the first water block from the pump outlet
double edit: i see what I did.. 35-38c is inside the case. Ambient room temps are ~26-30CEdited by giganews35 - 5/9/12 at 3:34pm
